The thick gel found in the leaf of the aloe vera plant has been used for thousands of years to heal a variety of topical conditions. In fact, aloe gel was one of the most frequently prescribed medicines in the 18th and 19th centuries. The gel is composed of 95 to 99 percent water along with glycoproteins and polysaccharides. Glycoproteins stop pain and inflammation, while polysaccharides stimulate skin growth and repair, making aloe gel an excellent cream for accelerating the healing process in burns and wounds. But aside from using the aloe gel to heal your skin, researchers have discovered drinking aloe vera juice can heal a broken heart. That is, preliminary research is beginning to confirm the beneficial use of aloe vera juice for preventing heart attacks and strokes.
Prevent a heart attack, reduce your stroke risk, and lower your blood pressure. Avoid medications, when possible—even avoid doctor and hospital visits!

What Is Aloe Vera Juice?
Aloe Vera Juice Health Benefits
What is aloe vera juice good for? There are a wide variety aloe vera juice benefits. First, it boosts the immune system and helps detoxify the body due to its high content of antioxidant nutrients. Second, research studies demonstrate that aloe juice can help lower blood sugar levels in people with type 2 diabetes.
Also, there is evidence that aloe vera juice can help ease constipation because of its high water content and enzymes, but it is generally not recommended for digestive issues as it can cause some abdominal cramping or diarrhea. (For digestive problems, other natural remedies such as probiotics or psyllium are recommended.) See this link for additional side effects and warnings.
Cholesterol and Triglyceride Help
Results of a study published in the Journal of Nutritional Science and Vitaminology showed that aloe administration lowered liver production of cholesterol by about 30 percent.
Additional research has shown that consuming aloe vera decreases LDL “bad” cholesterol levels and reduces triglyceride levels while increasing blood HDL, or “good” cholesterol.[3,4] This is very significant, as many natural remedies for cholesterol control work effectively at lowering LDL levels but do not always increase HDL levels. Therefore, using aloe vera juice to balance your total cholesterol ratio is uniquely beneficial.
Aloe Vera and High Blood Pressure
It is hypothesized that aloe vera juice is one of the key home remedies for high blood pressure and improve overall heart health in a number of ways: Because aloe vera juice contains a high amount of vitamin C, it enhances circulation and strengthens veins and arteries.
Other nutrients in aloe vera juice help to dilate the capillaries and boost blood oxygenation, thereby offering therapeutic benefits on the cardiovascular system.
In one study of more than 5,000 patients over five years, successful results were reported after administering aloe vera combined with psyllium fiber to participants. Aside from reductions in total cholesterol, triglycerides, and blood sugar levels, the following results were noted:
- There was a decrease in frequency of angina attacks during the study period and patients had their drug dosages gradually reduced over time.
- By the end of the study, 85 percent of the patients had their heart rhythm return to normal on an ECG.
- A total of 2,151 of the patients were originally diagnosed with hypertension (high blood pressure); all of the patients taking beta blockers, calcium channel blockers, or diurectic medications to treat their hypertension and angina had to have their medication reduced to at least half their prescribed dosages.
The Bottom Line
Here’s a summary of the six aloe vera benefits for your heart, based on the cited research reports:
- Lowers LDL cholesterol
- Increases HDL cholesterol
- Reduces triglycerides
- Lowers blood pressure
- Stabilizes heart rhythm
- Reduces occurrence of chest pain (angina) attacks
How to Take Aloe Vera Juice
One research study found that taking 10 mL or 20 mL of aloe vera water or juice orally daily for 12 weeks can reduce total cholesterol by about 15 percent, low-density lipoprotein (LDL) cholesterol by about 18 percent, and triglycerides by about 25 to 30% percent (5 or 10 mL). Then gradually increase the dose based on the manufacturer’s (or your doctor’s) instructions.
Aloe vera is also available in freeze-dried capsules. Follow the dosage directions on the package when taking aloe in capsule form.
If you take any medications, talk with your doctor or an integrative physician before taking aloe vera juice and be sure to read the precautions below.
Aloe Vera Juice Side Effects and Precautions
1. If you’re currently being treated with any of the following medications, you should not use aloe vera without first talking to your doctor:
- Medications for diabetes: One of the health benefits of aloe vera juice can also be one of its main side effects, as it helps lower your blood sugar level. This may be potentially dangerous for people already suffering from low blood sugar.
- Digoxin and diuretics: Because taking oral aloe can decrease levels of potassium in the body, aloe latex should not be used by people taking diuretics (water pills) or digoxin (a medication used to treat irregular heart rhythms and congestive heart failure). These drugs also lower potassium levels in the body, so a combination of aloe and digoxin or diuretics could cause potassium levels to fall too low.
2. Aloe-emodin, aloin, and aloe latex (yellowish substances naturally present just under the skin of the plant) are classified as anthraquinones, a type of laxative. Since these substances may have toxic effects, some medical experts recommend avoidance of aloe juice that contains anthraquinones. One consideration is to use one of the commercial aloe vera juice products that have the anthraquinones removed. Also, it’s almost impossible to remove the anthraquinones when trying to make your own juice from the plant. So if you want to use aloe vera juice on a regular basis, it’s highly recommended you use one of the commercial aloe vera juice products. When purchasing a “whole leaf” aloe vera juice, make sure the label clearly states the “emodin” or “aloin” has been removed. Or, you can purchase aloe vera juice made from the “inner leaf” or “inner gel,” which does not contain these anthraquinones. Again, do not try to make aloe vera juice at home; instead, purchase one of these products.
3. Aloe vera juice, when consumed in an excess amount, can lead to abdominal cramping, diarrhea, dehydration and electrolyte imbalance.
Reduce Your Risk of Heart Attack and Stroke
The preliminary research studies on aloe vera juice are promising. But to achieve the best results for heart attack and stroke prevention, it is recommended you combine aloe vera juice with other health strategies such as diet and exercise. Some believe it’s beneficial to take vitamins and other supplements and even certain foods, such as chia.
